This series is discussing the idea that not only does success bring happiness, but happiness also brings success.  Previously, we found that happiness helps people to have better careers and better relationships.  Today, we’ll see that they also have better health, too.

The authors of the paper put the question this way: “Is happiness associated with superior physical and mental health?”  I like the sound of that!  Superior physical and mental health – that has a nice ring to it, that’s definitely something I want.  In fact, that’s what I want on my gravestone: “Here lies Warren Davies. Had superior physical and mental health.”

As with the previous two articles, I’ll show some of the findings from cross-sectional/correlational studies first (comparing happiness with health at one point in time):

Mental Health and Happiness

• Happier people have fewer symptoms of psychopathology (eg., depression or schizophrenia)
• The absence of positive emotion is a distinguishing feature of depression
• Happier people are less likely to suffer from social anxiety or phobia
• Happy people are less likely to use drugs
• Unhappy teens are more likely to show delinquent behaviour

Physical Health and Happiness

• Happy people have smaller allergic reactions
• In one study, positive mood was associated with fewer visits to the hospital, less medication use, and other positive outcomes in people with sickle cell disease
• Optimism is associated with less pain in ageing war veterans
• Optimistic women are less likely to deliver low-birth weight babies

Just like before, the above findings can only tell us that “happiness” and “superior physical and mental health” tend to occur together in people.  They can’t tell us what causes what, because measurements were only taken at one point in time.  Plus the mental health findings are pretty obvious – no one’s getting a Nobel Prize for those discoveries!

So, here are the longitudinal study findings to save the day (studies trying to find out if more happiness now means better health later):

• Happiness measures taken from 5,000 people were reliable predictors of how many days were missed due to illness, and days spent in hospital, over the next five years
• People with higher positive mood had lower incidences of stroke 6 years later
• Happy hockey players experience fewer sports-related injuries over the ensuing season
• Happier people were found to be less likely to die in automobile accidents (!)

There are a few more findings, but you get the point.  No doubt good health is a source of happiness, but interestingly, happiness is a source of good health and a long life too.  I’ll look at the reasons this might be in the next article, but it appears there are both direct and indirect effects.

So now you know the different ways that happiness can improve your success in life, as well as the the other way around.  Generally speaking, happier people do better at work, earn more, have more friends, are luckier in love, and enjoy better health.

In the next article we’ll look at how happiness is thought to bring these benefits. By the way, you can find more info on health and happiness here.

This series was based on the below paper published in Psychological Bulletin by Sonja Lyubomirsky, Laura King and Ed Deiner – three big names in positive psychology.  It was a huge effort, they analysed 225 studies with over 275,000 participants in total!  All three researchers have books out so if you like the stuff in these articles, stick their names into Amazon and see if there’s something you like!

Apart from the side-splitting humour, all the points in this article came from this reference.  If you’re looking for the original studies, get the pdf of the above reference and do a Ctrl+F (or Apple+F) to search for the finding you’re looking for.  Then find the study in their reference list.

This series is discussing the idea that not only does success bring happiness, but happiness also brings success.  Last time we found that happiness helps people to have better jobs and earn more money; today we’re going to see whether they enjoy better relationships too. I’ve already written articles on happiness as it relates to marriage, and social relationships, so I’ll just add a few extra findings today.

Romance, Marriage and Happiness

• One of the strongest findings in happiness research is the positive correlation between social relationships and happiness
• Happy people tend to have more friends and more social support
• Happy people are more satisfied with the friends they have and less prone to jealousy of other people
• On the other hand, loneliness has a negative correlation with happiness, and a positive correlation with depression
• Happy people are good for society – they spend more time volunteering

More Evidence

Just like last time, the above evidence in cross-sectional, which means you can’t determine from it what is the cause and what is the effect.  You need longitudinal evidence for that – studies that track a variable over time.

Although studies tracking happiness and relationships over time are sparse, there are a few.  One paper reported that happier people received more emotional and tangible assistance from others, over a year after the happiness measures were taken.

In terms of romance, it’s a two-way street  – if you’re happier, you’re more likely to find a partner and get married, and when you get married, you receive a boost in happiness that lasts over the long term.   For example, college yearbook entries for a sample of women were analysed for how much positive emotion they conveyed.  Amazingly, this could be used to predict how satisfied they were with their marriages, 31 years later!

These findings fit into the authors’ theory that happiness is a signal to expand as well as a result of successful expansion – it’s a kind of dry way of putting it, but when you get married you effectively double your resources.  You pool tangible possessions, money, you both have access to more emotional support, meet new people from the other family and so on.  So it makes sense that marriage would bring happiness.  Oh yeah, plus there’s all the love, sex and mushy stuff too.  Let’s not forget that.

So far so good for the theory – happiness can be a cause of social and romantic success, not just a result of it.  Next time we’ll ask whether happiness improves our health.

Let’s look at happiness from a different perspective.  Most people see happiness as a response to good things happening; a natural assumption to make, considering that when good things happen, it makes us happy.  But the evidence is piling up that happiness is also a cause of good things happening.  And by ‘good thing’, I don’t mean that people smile at you more because you’re cheerful, or some other pleasant but ultimately feebly benefit.  I mean a better career, more chance of finding love, better resistance to disease, and many other things.

How is happiness supposed to bring success?

Happiness is a signal that things are going well.  You’re safe, you have access to the resources you need, and you’re making progress towards your goals – life is good.  When things are good, it makes little sense to put walls around you and carefully guard everything you have (a hallmark of ‘negative’ emotions).  It’s a better time to expand, take on new goals and challenges.

Imagine you’re really rich.  A multi-millionnaire if you like.  Someone comes to you with a proposal for an investment.  It’ll cost you £10k, and it’s risky, but the return could be pretty good.  Do you do it?  Probably!  £10k is small change to you, you wouldn’t even notice the loss.  That’s an extreme example, but basically it’s a similar principle with happiness.  It encourages a person to expand, because the mind thinks opportunity is knocking.  Therefore happy people should get more success, because their emotional state essentially makes trying to succeed more appealing.

Now the researchers in this field aren’t saying that the direction of causality is only from happiness to success.  This wouldn’t even logically follow.  If you got some success, your resources and abundance would increase, which according to this theory is one of the reasons you get happy in the first place!  So if it’s true that happiness contributes to success, it can only be true that success contributes to happiness as well.  So you could get a kind of upward spiral (though other things, like adaptation, complicate the matter).

This series of posts is based on a huge analysis done in 2005 (1), see the footnotes for more information on the researchers.  They pulled together a huge amount of evidence together to see if this perspective on happiness holds up, and find that it does in three areas: work, love and relationships, and health.  Here we’ll look at work, but first let’s make sure we know what we’re talking about.

What do they mean by ‘happiness’?

The definition of happiness in this study was slightly different to the one normally used in studies (life satisfaction or subjective well-being, see what is happiness?).  The definition here, is the experience of frequent positive emotions, and less frequent (though not completely absent) negative emotions.

Why this different definition?  Because in this framework, it’s positive emotion that leads us to pursue new goals and opportunities in the moment – rather than how pleased we are with life generally.

So technically they are saying that success comes from from a happy state, not a happy disposition, but, a person with a happy disposition will be in a happy state more of the time.

What is success?

What do you think success is?  You might see success as lots of money and a family.  A man in the Mursi tribe of Ethiopia might see success as living to the age of thirty and marrying a woman with a 10″ ceramic plate in her lip.  So success means to do well relative to the goals valued by the society you’re in.

As this study was done in the US, the researchers decided to use work, love and health as the markers of success.

Work

If you’re reading this from anywhere outside of a Western culture, let me assure you, we love to work!  Well, most people complain about work, but they still get up at 7am every morning to do it.  There’s very little I’d choose to get out of bed for at 7 in the morning, and yet I’ve woken up at that time and earlier, thousands of times, to go to work.

Work gets a bad rep, but it’s pretty normal human behaviour; even back in hunter/gatherer times we had to, well, hunt and gather.  We assume we did anyway, based on the tools and other goodies we’ve dug up.  I’ve never actually met a 40,000 year old person so I don’t really know for sure, but it’s a safe bet.  Work is just the name given to activities which allow people and groups to build their resources.  In modern life, we get tokens called ‘money’ in exchange for work, which we can exchange for the work of other people.  Work also (potentially) allows us to do something meaningful, and produce the things our society needs.

Plus, as we live in a meritocracy, the better we are at work, the more we produce for society, the more money tokens you get and the more good stuff we can exchange them for.  That’s one of the reasons we want to do well at work.  So are happy people more successful at work than their unhappy colleagues, generally speaking?

Happy Workers are Successful Workers

Here are some interesting findings about happiness in the workplace. Happier people:

• Are more likely to get job interviews
• Are more likely to receive positive evaluations once on the job
• Are more productive
• Handle managerial roles better
• Have less ‘job burnout’
• Tend to be more satisfied with their jobs
• Earn more money

It seems clear that happiness and success go hand-in-hand at work.  But these are all correlational studies, and you’ve probably heard the catchphrase “correlation does not mean causality.”  In other words, they may go together but we don’t know which is the cause and which the effect, or whether both are an effect of something else altogether.

So more evidence is needed.  The next step is longitudinal evidence.  This is where something is measured at time 1, then something else (or the same thing) is measured at time 2.  In this case, the researchers looked for studies that measured happiness first, then symptoms of success months or years down the line.

They found a few.  For example. after a job interview, happier people are relatively more likely to get a second interview three months down the line.  In another study, people with more positive emotion at age 18, were more likely to be financially independent, and generally doing well in their career.  The researchers also found that doing well in their career made the participants happy too – so the link between happiness and career is a two-way street, as expected.

Happy people also earn more money tokens!  One study found that happier Australians were more likely to receive an income increase in the near future, compared to their less happy mates.  A similar result was found with a Russian study panel.  Yet another study found that students who were more cheerful in their first year of study were earning more money some 16 years later.

In other words, more happiness now = more money and better career later.

So, in terms of career and money, it seems that happiness is not just a consequence, but also a cause.  The idea that happiness causes success gets some support from the workplace.  Next time, we’ll look into love and relationships.

Roads and ‘Success’ by Toban Black, Happy Workers by fauxels.

These two dominant models of strengths are slightly different in concept.  Gallup’s Strengthsfinder is more workplace-oriented, helping people to do better in their careers and organisations to work better.   Perhaps performance-oriented is a better term.  Values In Action (VIA), which we looked at in depth earlier, is character-oriented, helping people to achieve virtue.

First of all, I should say that StrengthsFinder doesn’t measure something Gallup calls ‘strengths’.  They measure ‘talents’, which are defined as natural ways of thinking and behaving, and by adding skills and knowledge, they say talents can become strengths, which they define as consistent near-perfect performance.  Since SF talends and VIA strengths are the same thing, I’ll just call talents strengths for consistency.

Given these basic conceptual differences, I wondered whether their respective questionnaires would return slightly different results. If you look at the list of strengths below, you’ll notice there are overlaps, but maybe these labels aren’t measuring the same psychological constructs. Maybe ‘Positivity’, measured with the workplace in mind is different to ‘Optimism’ measured with virtue in mind.  Here’s the list of strengths in each model:

The bold headings for the VIA are the virtues, the strengths below them are the routes to expressing that virtue.  These categories were not empirically determined, although there are arguments as to why they’re distributed as such.

The first thing you’ll notice is that there are more strengths in the StrengthsFinder, but the second thing you’ll notice is that the VIA model has no compunctions about grouping similar strengths under one label.  Most of the time they are similar, but some of them I feel might be better off  separated.  For example, ‘hope’ and ‘optimism’ are similar but not quite the same thing; hope accepts the possibility of failure where as optimism is almost dismissive of failure.  And ‘future-mindedness’ is put under the same label, even though if you were future-minded and pessimistic, your forward thinking nature could be called a strength but it wouldn’t be picked up as well by the VIA questionnaire.

The VIA strengths are (primarily) meant to be positive and wholesome, to not have potential to detract if not used or attract jealousy when they are.  If more people exercised these strengths, the world would be a better place, both for the individuals and the people they affect.  This is kind of the point.

StrengthsFinder is (primarily) about performance, becoming more effective and more productive.  This does not mean you can’t be virtuous with the StrengthsFinder strengths or effective with VIA: it’s just worth keeping in mind the intentions of the models when you’re deciding which one to use either for your self or in applied settings.

For example, I’ve argued elsewhere that it’s a good idea to stick to your strengths, on the basis that maybe we can’t “Do anything we set our minds do,” and even if we can we have to take the quality of the journey into account, and it’s less satisfying against the grain (though to be fair the experimental evidence is still a little thin).  But with the VIA model based on building character, you might find something like love or honesty at the bottom of your profile.  It seems incorrect to say to someone “Forget being honest; it’s not your strength so you might as well just lie to people!”

If your aim is to improve your performance in some domain, it might make more sense to go with StrengthsFinder or use common sense when interpreting your VIA profile; focus on the top strengths, but be aware there might be benefit in developing weaknesses of character while there’s possibly less benefit in developing performance-based weaknesses.

As I said before, there is a lot both models agree on.  Ultimately, it’s impossible to know whether the strengths listed in both models relate to the same things without looking at both questionnaires, and doing a dedicated study and analysis – which hasn’t been done as far as I am aware, because the Gallup StrengthsFinder is copyrighted intellectual property.  But I expect they are very close, so out of curiosity I did my own experiment; I took both tests to compare the results.

I went to the Authentic Happiness site to take the VIA Inventory of Strengths, then the next week I took StrengthsFinder 1.0, using the code from a Now, Discover Your Strengths book.  The Authentic Happiness website stores your results, so I intentionally didn’t look at them after I’d finished so as not to unconsciously influence my answers to the StrengthsFinder.

With a sample size of 1, my experiment is flawed, but still, the results were pretty interesting.  These are my profiles:

My VIA Strengths

Curiosity and interest in the world – You are curious about everything. You are always asking questions, and you find all subjects and topics fascinating. You like exploration and discovery.

Love of learning – You love learning new things, whether in a class or on your own. You have always loved school, reading, and museums-anywhere and everywhere there is an opportunity to learn.

Hope, optimism, and future-mindedness – You expect the best in the future, and you work to achieve it. You believe that the future is something that you can control.

Judgment, critical thinking, and open-mindedness – Thinking things through and examining them from all sides are important aspects of who you are. You do not jump to conclusions, and you rely only on solid evidence to make your decisions. You are able to change your mind.

Caution, prudence, and discretion – You are a careful person, and your choices are consistently prudent ones. You do not say or do things that you might later regret.

My StrengthsFinder Strengths

Harmony – You look for areas of agreement. In your view there is little to be gained from conflict and friction, so you seek to hold them to a minimum.

Intellection – You like to think. You like mental activity. You like exercising the “muscles” of your brain, stretching them in multiple directions. This need for mental activity may be focused; for example, you may be trying to solve a problem or develop an idea or understand another person’s feelings.

Futuristic – “Wouldn’t it be great if . . .” You are the kind of person who loves to peer over the horizon. The future fascinates you. As if it were projected on the wall, you see in detail what the future might hold, and this detailed picture keeps pulling you forward, into tomorrow.

Learner – You love to learn. The subject matter that interests you most will be determined by your other themes and experiences, but whatever the subject, you will always be drawn to the process of learning.

Focus – “Where am I headed?” you ask yourself. You ask this question every day. Guided by this theme of Focus, you need a clear destination. Lacking one, your life and your work can quickly become frustrating.

I have to say, these are pretty accurate for me.  Curiosity and love of learning are probably my main drives, tempered by my caution and critical thinking.  So I’m curious about the world and how it works, but I don’t go jumping in caves just to see what’s in them, and you won’t find me at tarot card readings.  I also like to know as many facts as possible before making a decision, and get a both sides of a story.

My StrengthsFinder results propose harmony, which is true, I’m the “can’t we call get along?” type, and focus which is also accurate as I’m more of a ‘choose a destination and go there’ person than a ‘go with the flow’ type, which is probably where the futurism comes from.  Harmony also apparently covers looking for harmony between ideas as well as within groups.

So, it seems you now have me at a disadvantage; you know so much about me, and I know so little about you.  All I know is that odds are, you live in the UK or US, are viewing this site with Microsoft Internet Explorer, and will stay here for 5-15 minutes before you move on.  Doesn’t seem quite fair…

Anyway, the strengths that appear in each output are very comparable. The outputs are roughly the same, but flipped. Look at it this way:

In most cases, the questionnaires results have equivalents.   You could make a case that ‘Hope and Optimism’ is similar to ‘Focus’, but it’d be a weak one; focus is more about getting to a certain place in the future rather than having a time-perspective pointing that way most of the time.  ‘Caution’ and ‘Harmony’ have no equivalent, although my 6th strength on the VIA list is ‘Forgiveness and Mercy’, which is similar to Harmony.

Even though this proves nothing generally, maybe both questionnaires are measuring similar things. It also makes it easier to recommend one; if they are measuring similar things, go for the VIA at Authentic Happiness – it’s free. If you want to try StrengthsFinder, you’ll need a code from the book StrengthsFinder2.0 to take the latest version of the test (my results above came from version 1.0).

If you do take one of the tests, I dare you to put your results in a comment.  I’ll feel less exposed. 🙂

Music has a remarkable ability to conjure up strong emotions in people.  It can cheer you up, bring you down, and in the case of boybands, cause severe anger and disgust.  And it’s old; some scientists believe music even predates language, this based on flute-like instruments dug up in France, believed to be over 50,000 years old.  But music is a bit of an evolutionary puzzle.  It’s hard to think of any survival value it may have brought us; a niche it filled better than any other human faculty.  So why do we love music so much?  What’s going in inside our skulls when we hear music we enjoy?  What music makes the best pick-me-up?

Happy music = Music you like

Starting with the latter question, there are a few ways to figure out scientifically what happiness-inducing music might be.  The first would be to give people a CD containing music of different varieties, and measure their happiness before and after a week-long listening binge.  This hasn’t been done yet, to my knowledge.  The second way would be to hook people up to devices that measure their physiological state, and play them different types of music to see what happens.  A few studies like this have been done: here’s an example.

Music-lovers were given a PET scan while they listened to one of their favourite pieces of music; something that gave them the “chills,” or “shivers-down-the-spine.”  One participant chose Barber’s Adagio, which, rather freakishly, my itunes just started playing as I write this.  Fair enough, I happen to be listening to The Most Relaxing Classical Album of All Time (classical music is the only type that doesn’t distract me from writing), but still…

Back on track.  When you listen to music, it’s processed in brain areas associated with, among other things; language, memory (short- and long-term), and emotion.  But when that music is something you really like, something that gives you chills, the brain areas involved in pleasure and reward light up too. (1)

These reward circuits turn on when you eat, have sex, or do pretty much anything that’s naturally rewarding.  They are also activated directly by many drugs, which is partly why these drugs are so addictive.  In this study, brain activity when the music was played was similar to that of euphoria and pleasant emotions.  The areas the music activated are crammed with opioid receptors (eg., endorphins).  In fact, another study found that blocking these opioid receptors with a drug called naloxone reduces the chills people get from music. (2)

But this is definitely all happening through music to your own taste – when the participants listened to ‘control’ music, that they didn’t choose themselves, there was less brain activity in these areas and fewer reports of chills.  So using music to bring pleasure and happiness requires a knowledge of your own personal tastes.

Music and Happiness

These internal goings on are all very interesting, but “music you like makes you happy” doesn’t really satisfy as an answer.  It’s obvious: of course the music we like makes us happy.  That’s why we like it.

What we’re really asking is, what type of music, on average, brings out the most positive emotion in people.  Accounting for taste is easy – you just average it out with large enough sample sizes, and look at the trends in the data.  This is how psychology studies are typically done.  It’s not a ‘hard’ science like physics, so researchers drown out individual differences with big sample sizes.

So, what’s the utilitarian approach to happiness music?  If you had a group of people, and you want to make the group a little happier overall, what’s your best bet?

Well, some studies compared different aspects of music with emotion and physiological responses.  Although there were some connections, for example, up-tempo music in a major key evoked similar responses to positive emotions, and consonant music was rated more pleasant than dissonant (3), as one paper pointed out, “this [preference for consonance] presumably indicates that listeners have internalized the tonal rules of music in their culture and react to violations of these rules.” (2, p383)

So for now at least, we might be stuck with the subjectivity answer.  There is some evidence that our musical tastes may be innate, for example, 4 month-old babies seem to prefer consonant to dissonant music (4), but the evidence doesn’t seem conclusive.  What I really wanted, but didn’t find, was a study comparing the effects of different genres on various emotions.  Does jazz flute make you happy?  Does emo make you depressed?  Do boybands make you want to puke?  Big questions, but apparently, scientists have not yet considered them a valuable addition to the knowledge base.

Music and Memories

As mentioned earlier, listening to music activates brain areas associated with memory.  I’m sure you have some songs that remind you of the good times – a holiday, a particular person, a bar you used to like going to.  Memories work by association, and when you hear these songs the brain areas associated with the memory turn on too, sometimes bringing back feelings along with the memories.

In How to be Happier, I mentioned a study on reminiscence.  It’s a strange thing to consider, but people who spend 10 minutes or so per day reminiscing about good memories of the past, became more satisfied with their life in the present.  Some participants were asked to use items to aid their reminiscence; trinkets from the past that ‘brought back memories’.  I don’t see a reason that music couldn’t do the same thing.

Music and People

As I’ve said before, building social relationships is among the biggest – if not the biggest – things people can do to become happier.  So by extension, music will make people happier if it’s part of some social event. This will include live music, playing music in a band, or anything that involves other people as well as music.

What kind of music can make you happier?

• More than any specific type of music, music that’s to your own taste is most likely to bring pleasant emotions
• Songs that bring back happy memories may also work, if you reminisce while listening
• Live music will also work, if you take your friends along with you
• Failing all the above; if you’ve been exposed to western culture: consonant, up-tempo music in a major key, is the best choice

In positive psychology, most theories of positive emotion have focused on discovering their relative costs and benefits to humans. These theories, to a greater and lesser degree, see positive emotions as being evolved adaptations to our environment. Greater mood brings wider though-action repertoires, allowing us to build our resources (1), they regulate our motivation to work towards goals (2), and when in the right balance with negative emotions, provide optimal conditions for mental health (3).

But all life on Earth is intertwined; could it be that our positive emotions exist not only for our own benefit, but to the benefit of other species, too? Researchers Haviland-Jones, Rosario, Wilson and McGuire (4) argue that they do. What species could be manipulating our positive emotions to their advantage? Could it be the intelligent dolphin? Man’s best friend, the dog? Or perhaps our closest cousin, the chimpanzee?

Nope. It’s the simple flower!

Do these flowers cheer you up?(Credit: Per Ola Wiberg)

The logic behind this argument is that there is an evolutionary ‘niche’ open for species that can elicit emotional rewards in mammals. The first step towards testing this idea, is to establish an emotional connection between humans and flowering plants; something romantics have known for centuries!

In a series of studies, Haviland-Jones et al report that:

• When women were given flowers, they always responded with a ‘real’ duchenne smile, and reported more positive moods three days later.
• When men or women were given a flower, they responded with a duchenne smile and engaged in more prosocial activities (compared to control conditions of being given a pen or nothing).
• Flowers given to elderly people resulted in more positive mood and improved episodic memory!

The researchers also reported other “unusual emotional displays that they were unprepared to measure,” (4, p122), including:

• Hugs and kisses.
• Invitations to participants’ homes for refreshments.
• ‘Thank you’ cards and letters – some with photographic evidence of the continuing beauty of the bouquet.

As they sum up – “In many years of studying emotions, we have never received hugs and kisses, thank you notes or photographs, not even for candy, doghnuts, hats, gift certificates, or direct monetary payment; flowers are different.”

What about this one? (Credit: Flowery *L*u*z*a*)

These findings are difficult to account for using the theories under the positive psychology umbrella. The emotion does not seem to be relevant to a goal process, or related generally to receiving a gift. And why would the presentation of flowers bring a broadened thought-action repertoire? Perhaps something to do with Fredrickson’s cognitive maps; as flowering plants were part of our ancenstral environment, could their presence trigger a positive emotion to allow greater awareness and therefore knowledge of the environment?

Haviland-Jones et al suggest three better explanations:

1) Learned associations between flowers and happiness from positive social events

Possibly true, but typically the socialisation of positive emotions and flowers is specific to women, and the studies also found effects in men. Additionally, learned associations do not account for the prevalence and meaning given to flowers cross-culturally. Still, this can’t be ruled out without studies in cultures that place little or no significance on flowers – if there are any.

2) Evolutionary food association

Rather than a positive social event, perhaps flowers are associated with potential foraging success – as they signal the current or future availability of nuts and fruits; nutritionally dense foods.

3) Flowers evolved as human mood enhancers

Perhaps the sensory aspects of flowers directly influence positive human moods. This reaction to flowers would be expected without learning an association between flowers and happiness, but would make learning such an association easier.

How could this all be working? Emotional processing occurs in a specific part of the brain, based on certain ‘rules’ applied to the input to this area. Over vast periods of time, and where it is in their interest, organisms attempt to access the ‘rules’ of other organisms and adapt to them. It’s a kind of evolutionary cold war, all happening through the trial and error of natural selection, without any conscious or deliberate direction (an important point).

Flowers have adapted to our preferences in a number of ways, it seems. We have a preference for symmetry, we have a preference for certain colours, and we may also have a preference for certain smells. These preferences all evolved for specific purposes (pattern recognition, to distinguish between high- and low-protein leaves, etc), but because they are general preferences, we would not necessarily need to be exposed to a flower to be attracted to it – it is configured in a way that our brain ‘likes’, which triggers the release of chemicals that result in our positive emotions.

This may be serendipitous though, because the smells, colours and shapes of flowers may have evolved to attract the birds and insects with which their cross-species pollination efforts are usually associated. Either way, this configuration appears to be beneficial to the plants; for many species of plants, humans are the main agents of seed dispersal, even those that have no nutritious or medicinal value. They have discovered the secrets of our positive emotional response mechanisms, and have adapted themselves to exploit it. We’re being manipulated!

Although this idea is far from confirmed, and there are a lot of unanswered questions, the theory does provide an interesting angle on positive emotions that we maybe don’t consider in positive psychology. When we think of the purpose of positive emotions, we immediately think “How do they benefit us?” But for a fuller picture of the role of positive emotions, we might have to think about how they benefit other species, too.
